UNITED STATES PATENT @Erica CARL GEIER, OF OBERLANGENBIELAU, GERMANY.'

SPECIFICATION forming part of Letters Patent No. 597,577, dated January 18, 1898.

Application filed May 13, 1896. Serial No. 591,363. (No model.) Patented in England .Tune 6, 1896, No. 8,340.

Be it known that l, CARL GEIER, of Oberlangenbielau, Prussia, Germany, have invented a new and Improved Self -Oiler for Machinery, (which has been patented in England, No. 8,340, dated .l une 6, 1896,) of which the following is a full, clear, and exact description.

My invention relates to an apparatus for supplying a lubricant to machineryin motion, and has for its object to make the supply of the lubricant dependent on the speed of the parts, to provide means whereby the lubricant will be supplied at regular intervals so as to keep the shaft or other part constantly lubricated, and tooperate a suitable alarm whenever the supply of the lubricant in the storage-tank has become nearly exhausted.

To these ends my invention consists in the particular construction and arrangement of parts hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional elevation showing the application of my invention to a shaft. Fig. 2 is an end view of the said device with parte omitted. Fig. 3 is a detail section on the line 3 3 of Fig. 2.

A indicates the shaft to be lubricated, the bearings of which are provided with suitable oil-supply channels A. At a level above said shaft is located the tank a., constructed of suitable material and provided in its top Z) with an opening c, through which the tank may be filled. At each end of the tank a notch LZ is provided between the tank proper and its cover or top, and said notches serve as bearings for a horizontally-arranged wire or rock-sl1ai`t e. Said wire is provided within the tank a with two eyes f, each supporting a screw f formed at its lower end with a hook or eye and receiving at its upper end a win ged nut serving to adjust the screws vertically. From each of the said screws is suspended a lead plunger or piston h, whose lower end is tapering or conical and fits into the upper end of a lubricating-tube h', adapted to feed the lubricant in drops tothe oil-channels A'.

A sieve g surrounds the plunger h, so that the aperture closed by said plunger may not become clogged. Exteriorly of the tank a the rod e is curved at one end to form a crank or frame i', which is adapted to be operated by an eccentric on`the shaft A or by a cam or equivalent device. Thus while the shaft is rotating the rod e will constantly receive a rocking motion. In consequence thereof the plungers Zi will be alternately raised and lowered, thus periodically uncovering the outlets leading from the tank a to the tubes 7L', and thus the shaft A will receive approximately the same supply of lubricant at each revolution, and as the motion of the plunger ZL depends on that of the shaft the supply of the lubricant will be proportioned to the rotary speed.

In order to automatically give an alarm when the supply of the lubricant in the tank is nearly exhausted, l provide the following device: The end of the rod e opposite t0 that carrying the frame 'i is extended downwardly along the end of the tank and then returned to form a crank 71;, composed of two runs of the rod. Between the runs of the rod forining this crank is received a wire Z', which eztinto the same in two brancl1es,terminatiugin floats Z, adapted to rise and fall with the liquid in the tank. Tubes m serve to guide the wires Z' where they pass through the top ZJ of the tank. The outer end of the wire Z,which fits between the runs of the rod forming the crank 7c of the wires Z, has its lower end liked to a transverse bar Z2, the ends of which extend along the inner sides of the runs of the crank when the bar is in the position shown by full lines in the drawings. Fixed to the rod Z is a rod Z3, running' horizontally to the bell Zt' and carrying a clapper ln,engagiug and sounding the bell. When the crank Zi; rocks and when the lower end of the rod Z has been moved to the position shown in Fig. 2. the` c by dotted lines in the drawings, the'hammer n will be raised to such a positionthat al* though it receives a reciprocating Lor oscillat- Having thus described my invention, Iv

claim asnew and desire to secure by Letters Patentl. In alubricati-ng apparatus, the combination with a tank having an outlet-orioe, of a rock-shaft, a plunger capable of closing the outlet-orifice and-having connection with the rock-shaft by which the plunger is moved,al

- crank carried by the rock-shaft, a rod movable vertically along the crank and vibrating byengagement with the outer end thereof, a ham@ mer connected to the rod,a bell carried by the tank, and a float lwithin the tank and con nected to the rod to move the same,-substan tially as described. 1

2. The combination with: a tank, ofa rockshaft, a crank on the rock-shaft, a rod Vibrated by and slidable longitudinally along the crank, a hammer carried by the rod, a bell carried by the tank, and a float within the tank and connected tothe rod, substantially as described.

3. The combination with a tank, of a Iioat within the tank, a rod connected to the float and slidable through the tank, a second rod exterior ofthe tank and connected to the first rod, means for vibrating the said exterior rod, a hammer carried by the exterior rod, and a bell carried by the tank, substantially as described.

4. The combination with a tank, having an outlet-orifice, of a rock-shaft mounted in the tank and having each end extending beyond the same, a crank at each end of the rockshaft, a plunger Within the tank and capable of closing the outlet-orifice thereof, a connection bet-Ween the plunger and therook-shaft,

a float within the tank, a rod connected to the lloat and movable through the tank, an exterior rod connected to the irst rod and being 1 vibrated by and slidable along one of the cranks, a hammer carried by the said exterior rod, and a bell carried by the tank, substantially as described.

5. The `combination with a tank, ofl a bell `carried thereon, a crank mounted to swing on lthe tank, means for swinging the crank, a

clapper, means carrying theclapper, such' meansbeing vibrated` by and movable along the crank, and a' float connected with the said means, substantially as described. c

6. The combination with a tank, of `a rockshaft mounted thereon, a crank carried by the rock-shaft,`means for swin ging the crank,

a rod vibrated vby and movable along the crank,the rod extending upwardly and thence horizontally overthe tank, a hammer carried by the lower portion of the rod, a bell carried by the tank, a ioat locatedwithin the tank and connected with the horizontal portion of the rod,and two yielding arms between which the horizontal portieri of the rod passes, said yieldingr arms being carried by the tank, lsubstantially'as described.

In witness whereof I hereunto set my hand in presence of two Witnesses.

CARL GEIER.
